SHORT CIRCUITS

In starting the car it is important to releasie the strirting pedal immediately the eri'girie beings to fire. t)b' not continue cfankirig engine| with starter ii dgition d'o:es not take plri'ce promptly. If necessary to use chdke iri s'trirtirig, do not keep tiie buttbri out too long, as the cylin'ders will then be flooded with p'etrol. Do not r'ace the erigi'rie iriimediately . up'ori star tirig or drive the caf at high speed uritil thororighly Wrirnled up. Scbring of pistons and cylinders riiay follow if this. precaution is not o'bserved. The furictibn of tlie oil riltef is to remove frbm the crankcase oil, all particles of dirt and cafbori! riot alrea'dy eliminated from circulation ,hy th'e oil Bririi^ sefeeri. When the filter is 'eritifiely free of dirt, its capacity is such that the.quantity of oil in the crankcase will pass throuigh the filter approximately every fiva miriutes, at a car speed of 25 ihiles ari horir. This rate of flow will gradually decrease until such time as the filter ceases to function, due tb - clogging, and while there is no definite iimit. to the life of the filteiirig unit, (it is advisrible to replace this unit after approximately 10,000 niiies use. Diffierent conditions of driving require var ying charging rates to obt'ain the best results from electrical systeni [ as a whole. For example: A physi- . cians car operated for short diistarices ; arid requiring frequerit starting and ' considerahle use of lights, needs a ■ higher charging rate than a car which ; is driven l'oriig distarices, with' little , use of lights. A thermostat is provided ; in the gerierator, for autbmafcic regu- ' lation of the charging rate to meet thesie varying requirements. The adjustriient of the thermostat should never b'e changed. If unusual driving conditions should make adjustmbnt of the charging rate necessary, this may be done by adjustment of the third brush, but the operation should he attempted only by someone thoroughly familiar with the proper procedure. Wh'eri ihe car leaves the manufacturer, the charging unit is adjusted to mbet the requireinents of the average driver. Dusty giass increased the glare of appro'aching headlights and for this reks'on the windshield should he wiped clean — inside and out — if a drive at niight is planned. That the clutch is a dry-plate type does not meap that no feature of the device needs lubricatiori. The relea.se bearing, one of the hardest worlring parts of the clutch, requires regular

lubrication in the case of niany.,cars. It is well td consult Ihe lubrication chart of-.the new car to make certain on this -jppint; . . 4 Adjristrneriti to • cylirider vaives should •never be made when the engine is cold. Valve stems wiil expand and so be longer when hot th'an when cbld; If the adjustment-is iriade "on a cold engine, the vaives may not seat prb|jbi4y Whsii HbE ixi M'cf, aJijusinients to Varipris brigdne parts should not be made when the motor is cold.
